To all whom it may concern:

Be it known that I, ROBERT Sco'r'r, a subject of the King of Great Britain and Ireland, and a resident of London, England, have invented certain new and useful Improvel'nents in Apparatus Particularly Suitable for Treating Oil-Seed and the Like; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to improvements in mill apparatus particularly suitable for treating oil seeds or the like, and has for its object to provide automatic means for delivering the material from the kettle or the like container to the molding press, performing the molding operation, and delivering each molded cake into convenient position for insertion into one of a series of oil expressing or other presses (hereinafter referred to as the presses), inserting each molded cake into its respective oil press, removing each loaded oil press from loading position and bringing an empty oil press into loading position, operating each loaded oil press to express the oil from the cakes,bring ing each operated oil press to unloading position and presenting each oil expressed cake ready for removal; whereby greater regularity of working will be attained, manual labor and time will be saved, and waste of material and cost of production will be materially reduced, in comparison with exist i110' mill systems or arrangements.

According to the present invention, a horizontal hydraulic ram for working the mold top slide at the bottom of the kettle is controlled by a valve closed by a cataract and allowed to open by a rotary frame carrying a series of vertically guided mold bottom plates and adapted to be driven through friction gearing so as to bring the bottom plates, on which the bags are placed by the operator, in succession beneath the mold box at the bottom of the kettle. The ram opens the top slide to allow the material to fall into the mold box onto the bagging on the respective bottom plate that is in position therebeneath' and closes the top slide to imprison the charge within the mold box. The rotary frame is adapted to be raised and lowered by a vertical hydraulic ram controlled by a valve allowed to close by the closing of the top slide and opened by a cataract. In its raised position, the frame is adapted to engage a stop which arrests it in position with one of the bottom plates beneath the mold box, and in its lowered position, the frame disengages itself from the stop so as to be free to be turned to deliver a molded cake without the latter fouling the mold box. The molding action effected by a second vertical ram controlled by a valve allowed to open by the closing of the top slide and closed by a cataract. ln rising, the compressing rain passes through one of a series of recesses in the rotary frame beneath the bottom plates and aids in preventing the rotary frame from turning. As the ram passes through a recess, 1t engages and raises the respective bottom plate above the frame into the mold box and compresses the imprisoned charge. The valves controlling the frame ram and the compressor ram are arranged so that the frame is lowered at the same time as the compressor ram is raised and so that the latter alone then serves as the means for preventing the turning of the frame. Further these two valves are arranged so that the com} ressor ram descends below the frame leaving the bottom pl ate thereon with the molded cake on the plate and the frame free to turn before the iframe rises, the latter movement taking place while the frame is turning.

Any suitable form of automatic folder may be applied for turning the ends of the bags over onto the molded cakes as the bottom plate is carried away from beneath the mold box. The turning movement of the frame transports each molded cake to one of a series of oil presses situate around a turntable and adapted to be brought one at a time into loading position at a convenient point on the borders of the radius of the frame.

The loading of the oil press is ellected by a loading device comprising a pair of arms adapted to be brought into position to engage the bag of each molded cake on the frame and to draw 4each bag and cake onto a plate of the oil press, by a horizontal ram controlled by a valve closed by the frame and opened by a cataract. The engagement and disengagement of the loading arms with and from the bag is controlled by a vertical ram controlled by a valve opened and closed by the loading arms. Each plate of each oil press with the molded cake thereon is adapted to be lifted into engagement with detcnt devices in the upper part of the press by vertical ian'ls controlled by a valve opened by the loading arms and closed by a cataract. The plates at the bottom of each oil press are brought to loading level for receiving the molded cakes by allowing small quantity of liquid to feed into the cylinder of the main expressing ram through a branch from one of the pressure pipes, this branch being controlled by a valve o-pened and allowed toI close by the fram-e. The turntable is given a p art rotation to bring a loaded press out of loading position and an empty press into loading' position by a horizontal ram controlled by a valve opened by the frame at the proper intervals and closed by a cataract. The cylinder of each main expressing ram is fed from overhead with low and high pressures from central boxes into which the mains from the accumulatore pass. The low and high pressure conduits to each oil press are controlled by valves opened and closed from overhead. The unloading of i each oil press is effected by the detent devices, which are adapted to allow the plates to drop one at a time, being operated by two rams controlled by two valves, each valve being opened and closed by its own ram and on-e valve being controlled oy a third valve opened and closed by the turntable rotating ram. As each plate drops, it is caught by a lowering device which automatically descends under the weight of the plate until the latter rests on the main expressing ram or on the topmost one of the already lowered plates, and is then automatically disengaged and raised for receiving the next plate.

rl`he invention is illustrated in the accompanying drawings, in which Figures 1 and 1a are a plan of part of a mill adapted according to the present invention; Fig. 2 is a section on the vertical plane 2 2 Fig. l; Fig. 3 is a section on the vertical plane 3 3 Fig. l; Fig. 4 is a detail view partly in section on 4 1, Fig. 1; Figs. 5 and G are detail views; Figs. 7 and 7a are a plan of another part of a mill adapted aocording to the present invention; Fig. S is a detail of a part incompletely kshown in Fig. 7 Figs. 9 and 92L are sections onthe vertical plane 9 9 Fig. 7, and 9a 92L Fig. 7a; Fig. 10 is a detail section on the vert-ical plane l0 10 Fig. 7a; F ig. 11 is an elevation at right angles to Fig. 10; Fig. 12 is a detail section on the vertical plane 12-12 Fig. 9; Fig. 13 is a detail section on the vertical A plane 13 13 Fig. 9.

Like reference letters indicate like parts wherever repeated on the dra-wings.

a is a steam jacketed kettle suspended or supported by any convenient means, not shown, so as to leave a clear space underneath for the frame hereinafter referred to to turn in.

al is an out-let leading to the mold box a2, at the bottom of the kettle, and a3, is a slide for closing the top of the mold box.

The slide a3, is connected to a hydraulic ram o, the cylinder o0, of which has a port communicating by a conduit b1, with an accumulator, and a port communicating by a conduit b2, with a valve chamber c, having a port communicating by a conduit, c1, with the accumulator, and an exhaust port c2.

The valve chamber contains an ordinary D or other suitable valve adapted to open the conduit b2, to the accumulator pressure or to the exhaust, c2. The ram o, is made of difere-nt areas at its ends and so that when the valve is open the accumulator pressure passing' through conduit b2, opens the slide c3, and when the valve is closed the accumulator pressure passing through conduit o1, closes slide a3, the pressure in conduit b2, exhausting through conduit c2.

The valve is connected to a rod, c3, coupled to a bell crank lever d, pivotally mounted at c. A. second bell crank lever f, is pivotally mounted at e, and is acted on by a weight f1. The inclined arm of lever f, has a lug f2, adapted to engage the inclined arm of lever (Z, so as to retain the valve in closed position. llvhen, however, lever f, is moved so as to raise the weight and disengage the lug from lever CZ, (as hereinafter explained) the accumulator pressure opens the valve. rlhe descent of the weight and the closing of the valve is controlled by a cataract f3, which may be adjusted by a-valve not shown.

g is a frame consisting of a plurality of arms mounted on a vertical spindle g1, serving as a ram and working in a hydraulic cylinder glo, with facility of vertical movement. rlhe spindle is slidingly coupled to a driving shaft g3, mounted in bearings g3", and driven from overhead by friction gearing g4. Each arm at its outer end is enlarged and formed with a recess g5; and the mold bottom plate g, is mounted above the recess and guided vertically by pins g". a4 is a stop for engaging the arms so that the respective bottom plates gs, are arrested in position beneath the mold box.

Each arm has a catch 97, adapted, just 'before the arm comes to position beneath the mold box, to engagevthe vertical arm of the lever f, so as to disengage the lug f2, from the lever d, and allow the valve in the chamber c, to open as aforesaid under the accumulator pressure.

rlhe cylinder gm,- has a port communicating by a conduit g8, with a valve chamber 7i. rllhe valve chamber has a port communicating by a conduit h1, with the accumulator, and an exhaust port 7L?, and contains a valve adapted to open the conduit .(78, to the accumulator pressure or to the exhaust h2. rlhe valve is coupled to a bell crank lever controlled by a second bell crank lever and cataract similar to those above described, excepting that the valve is retained in open position by the bell crank, and is closed by a tumbler b3, on a slide 7), connected to the ram b.

j is a ram for raising the bottom plates g, into the mold box a2. rlhis ram works in a hydraulic cylinder j", with facility of vertical movement. The cylinder has a port communicating by a conduit jl, with a valve chamber 7c. This valve chamber has a port communicating by a conduit 7.21, with the accumulator, and an exhaust port 7a2, and contains a valve adapted to open the conduit jl, to the accumulator pressure or to the exhaust 71:2. The valve is operated similarly to the valve in the chamber 71., excepting that the valve is retained in the closed posi tion by bell cranks 7a3, h4, and is opened by a tumbler b5, on the slide b4.

In order to insure that the ram y', shall not rise and compress the material in the mold box before the slide a3, is completely closed, the bell crank lever 71.3, may be coupled to a rod 7L, guided as at a5, and adapted to bear against the underface of slide bt, exceptingr when slide a, is in the completely closed position, when rod 71.5, can rise beyond the end of the slide Z2, Fig. 2. The descent of the ram (/1may be similarly controlled to insure that the frame shall not descend before the ram j, rises.

In the raised position the ram j, engages the recess g5, of the arm beneath the mold box and lifts the bottom plate g, into the mold box.

m is a series of oil presses mounted in a tank a, on a rotary turntable nl, supported by runners n?, on rails a, in a well nl. The turntable is so arranged and operated that while one arm g, is benath the mold box a?, the arm g, carrying the molded cake is opposite an oil press ready for insertion of the molded cake into the oil press.

0 is a pair of loading arms arranged just above the level of the plates g, and pivotally mounted at the inner ends on a ram 79, working in a hydraulic cylinder p0. The cylinder p0, has a port communicating' by a conduit p1, with the accumulator, and a port communicating by a conduit p2, with a valve chamber (j. The valve chamber has a port communicating by a conduit g1, with the accumulator and an exhaust port (12, and contains a valve adapted to open the conduit p2 to the accumulator pressure or to the exhaust g2. The ram 77, is made of different areas and so that when the valve is open the accumulator pressure passing through conduit p2, moves the loading arms inward, and when the valve is closed the accumulator pressure passing through conduit p1, moves the loading arms outward to the position shown in Figs. 7 and 9, the pressure in the conduit p2, exhausing through port g2. The I valve is operated similarly to the valve in the chamber 0, excepting that the valve is retained in the open 'position by hell cranks y, g1, and is closed by a catch, y, on each arm of the frame g.

1' is a ram working in a hydraulic cylinder 1'0, and carrying a wedge piece, r1, adapted when the ram is raised to open apart the loading arms, o, which are closed together, when the ram is lowered, by a spring 01. The cylinder it', has a port communicating by a conduit r2, with a valve chamber s. The valve chamber has a port communieating by a conduit. s1, with the accumulator, and an exhaust port S2, and contains a valve adapted to open the conduit r2, to the accumulator pressure or to the exhaust S2. The valve is opened by a catch o2, on the loading arms and is closed by a catch 0", thereon.

ml represents the plates of the oil press between which the cakes are pressed. These plates are brought to a common loading position level with the plates g, and just below the loading arms, as hereinafter explained.

t represents rains working in a hydraulic cylinder to, and carrying detents t1, adapted when the rams are raised to engage lugs on the plates fm", and lift the top one of the plates, m, into engagement with detents u, at the lower ends of rods u1, depending from the head of the oil press, and when lowered to engage underneath the top plate m1. Each cylinder, t", has a port communieating by a conduit t, with a valve chamber t. The valve chamber has a port communicating by a conduit fnl, with the accumulator and an exhaust port o, and contrains a valve adapted to open the conduit t2, to the accumulator pressure or to the exhaust v2. rlhe valve is opened by a tumbler o, on the loading arms and is retained in closed position by bell cranks, fus, '114.

fw is a branch conduit leading from one of the pressure conduits, hereinait'ter referred to, to the cylinder of the main expressing ram, m", and Q01, is a valve in the conduit fw, adapted to be opened and allowed to be closed by the hydraulic pressure, by the frame arms g, on their passing away from position in front of the oil press.

a' is a ram for tiirning the turntable, working in a hydraulic cylinder m0, supported from overhead. lhe cylinder has a port communicating by a conduit m1, with the accumulator and a port communicating by a conduit a, with a valve chamber y. The valve chamber has a port communieating by a conduit 1/1, with the aceu1nulator and an exhaust port y2, and contains a valve adapted to open the conduit m2, to the accumulator pressure or to the exhaust y2. The valve is operated similarly to the valve in chamber g, being retained in the closed position by bell( cranks ya, yt, and 'open by the catches gll, excepting that any suitable form of tripv gear is interposed so that only in every sixteenth (or other convenient number according to the number of plates in the oil press) operation will the valve be opened by the catches gll. In lmoving out-ward, the ram m, by means of a tumbler, x3, engages a frame on each of the presses in turn and turns the turntable to the extent of the distance between two oil presses.

" 'm2, m3, are respectively low and high pressure conduits leading overhead to each oil press m, from central boxes, m4, m5, respectively, into the centers of which the low and high pressure mains from the accumulators pass with gland tight iit. The low and high pressure conduits are controlled by valves m6, m7, respectively, openedand closed by racks or equivalent means, m12, supportedv from overhead. m8 is the valve box into which the conduits lm2, m3, open, and m9, is a conduit for the low andv high pressures leading to the cylinder of the main expressing ram.

The rods u1, are adapted to oscillate about their axes, and are each provided with a catch u2, which is so arranged that when the rods are oscillated only the bottom plate m1, will drop, the other plates being supported by the catches u2, and when the rods are restored to their normal position the remaining plates rest upon the detents u, and the catches u2 are out of operation. The plates, 1n-1, are recessed as at m10, tol permit of the engagement of the catches u2. rlhe rods u1, are caused to'oscillate by tumblers on two unloading arms, w3, connected by a cross head to two rams, ut, a5, working in hydraulic cylinders M40, uw respectively.

|The ram ut is for moving the unloading arms outward, and the ram a5, is for moving the unloading arms inward. rlhe cylinder M40, hasa port communicating by a conduit u, with a valve chamber u, and the cylinder M50 has a port communicating by a conduit u, with a valve chamber 1052. The valve chamber U42, has a port communieating by a conduit M43, with the accumulator, and an exhaust port u, and contains a valve adapted to open the conduit u, to the accumulator pressure or to the exhaust w14. The valve is opened by a catch um, and is closed by a catch uw, on one of the unloading arms ug. The valve chamber w52 has a port colnmunicating by conduit 1653 with a third valve chamber, u, and an exhaust port u, and contains a valve adapted to open the conduit M51, to the valve chamber u, or to the exhaust um. The valve is opened by a catch u, and is closed by a catch 1015, on the other of the unloading arms as. The valve chamber us, has a port communicating. by a conduit' u, with the accumulator, and an exhaust port, w62, and contains a valve adapted to open the conduit M53 to the accumulator, or to the exhaust uw. The valve is opened and closed by catches m4, x5, respectively on the ram so that the ram a5, cannot be moved inward when the ram is rotating the turntable as it then closes the conduit M53.

.e represents tumblers mounted on rods el, each working in a dashpot z2 and normally held up by being connected by a cord e, passing over a pulley et, to a counterbalance z5. When a plate is dropped as aforesaid, its weight on the tumbler e, overcomes the action of the counterbalance and the plate is lowered onto the ram m0. As the tumbler passes the ram it is freed from the plate and is raised by the counterbalance.

1t will be understood that in lieu of hydraulic pressure other suitable pressure might be used.

The operation of the apparatus is as follows: Speaking with particular reference to Fig. 2: The frame g, in its raised position and turning in the direction of the arrow (Fig. l) has brought one arm beneath the mold box against the stop a4. to position the arm carrying the usual bag actuated the bell crank f, so that the slide a3, opened to charge the mold box and closed to imprison the charge therein. The ram j, now rises to engage the recess g5, and press the plate r/G, into the mold box while the frame g, descends Fig. 5. The ram y', then descends and redeposits the plate with the molded cake ontov the lowered frame g, and then descends below the frame (Fig. 6), which is then free to turn under the action of the friction drive g4 (Fig. 3), and while turning rises and stops and presents the molded cake to one of the oil presses m. Speaking now with particular reference to Figs. 7, Ta: The arm g,.carry ing the molded cake in its bag, in coming to position closed the valve q, so that the loading arms 0, were moved outward-by the ram p. At the end of the outward movement of these arms, the catch 03, closes the valve s, and the ram r, descends, and the loading arms 0, close and engage the molded cake in its bag. The valve Q, then automatically opens and the loading arms draw the molded cake and bag onto the topmost plate m1. Toward the end of the inward movement of the arms 0, the catch 02, opens the valve s, and the ram r, rises and disengages the loading arms from the molded cake and bag. At the end of the inward longitudinal movement of the loading arms, the tumbler o4, opens the valve o, and the lifting rams t, raise the molded cake and plate m1, into engagement with the detent devices, u, which yield to allow the plate to be raised thereabove. The valve e, then In coming closes and the rams t descend. As the empty arm g, moves away from the loading position, it opens and allows to close the valve w1, and the plates mi, are brought to loading level again for receiving another molded cake. These operations are repeated until the press is full. The valve y, is then opened by the frame g, and the turntable is rotated one step by the ram a', and so on. As each loaded oil press is moved away from loading position, its low pressure valve is lirstly turned on by one ot' the racks m12, its high pressure valve is then turned on by another of the racks, and then both valves are turned oli' by two others of the racks. Each press in turn is then brought to unloading' position, and the rods u, are oscillated by the unloading arms u1, operated by the rams u, a, so that the plates m1, drop one at a time on the tumblers, e, and are thereby lowered, and the expressed cakes and bags are hooked oil? by an operator.
